"Enacted in 2010, the Tribal Law and Order Act (TLOA) requires the Bureau of Justice Statistics (BJS) to (1) establish and implement a tribal data collection system, (2) consult with Indian tribes to establish and implement this data collection system, and (3) annually report to Congress the data collected and analyzed in accordance with the act (P.L. 111-211, 124 Stat. 2258, § 251(b)). Indian country includes federally recognized reservations, tribal communities, and identified trust lands. Criminal jurisdiction in Indian country varies by type of crime committed, whether the offender or victim is a tribal member, and the state in which the offense occurred. […] This report summarizes efforts related to BJS's tribal crime data collection system during fiscal year 2017, including:  Tribal data collection activities: the Survey of State and Local Law Enforcement Agencies Serving Tribal Land, the Survey of State and Local Prosecutor Offices Serving Tribal Lands, the Census of Tribal Law Enforcement Agencies (CTLEA), and the National Survey of Tribal Court Systems (NSTCS);  Tribal participation in national records and information systems, including the National Criminal History Improvement Program (NCHIP) and the National Instant Criminal Background Check System (NICS) Act Record Improvement Program (NARIP);  BJS's most recent statistical findings on jails in Indian country and the AIAN population in the federal justice system; and  How to access tribal information on BJS.gov."
